No surprise then when I think that the concrete ball idea will be just another multi-million dollar (or Euro) failure as many other "green energy" ideas of the past -- hollow minds foster hollow concrete balls
The drive to find novel energy storage systems for all the "alternative" energy produced from wind-turbines and solar (photovoltaic) systems is fostering the most bizarre ideas.
Needless to say, government bureaucrats are just too happy to throw taxpayers' funds at any idea that promises to fulfill the quest. One of the latest "grand schemes" involves hollow concrete balls sunk into the depths of the ocean, the deeper the better and the larger the better too.
So, what am I talking about, specifically? Of course, hollow concrete balls, the latest scheme in the quest to provide "free energy," see the photo of a hollow concrete ball, nearby!
